5MW Offshore Wind Turbine Control Based on Pitch Joint Torque Controller

Abstract:

Modern control theory has been used to design a variable pitch controller based on disturbance accommodating. The controller realizes the optimal control which minimized the controller action and drive-train torque. A torque controller based on pole clustering had been designed to enhance drive system damping and to suppress torque ripple. The federated control of variable pitch and torque is adopted to reduce drive system dynamic torsional load, and has been verified by software MATLAB and FAST. Simulation result illustrated that drive system dynamic torsional load can be controlled to improve reliability of wind turbine and extend life of critical components by active control method.
